To Chi "whom it may concern:

1 engagement between whichis essential in Be it known that'l, JOHN M.Score, a citizen of the United States, residing at Racine, in the countyof Racine and State of Wisconsin, have invented certain new and usefulImprovements in Ball-Anchors, oi which the following is a specification.

My invention relates to rail anchors, that is, to dcvicesi'or preventingthe longitudinal creep of railroad rails.

One of the principal objects of the invention is to provide an improvedrail anchor in which the clamping or griigping engagement with the railis eliected through the instrumentality of a spring yoke, which isflexed when the device is applied to the "rail so as to exert a stresswhich absorbs vibration and takes up looseness due, for ekaniple, todifference in expansion and contraction between the metal oi the anchorand the rail, to slight retrograde movements as between the parts of theanchor, or to other causes, thereby preserving an intimacy of the parts-of ,the anthe anchor and the rail order that the device shouldbeefiective under service conditions.

A further object is to provide a rail anchor which, 'wliile having thenecessary strength, will-beextremely light in weight.

chor and between This is unimportant consideration because of the savineffected in manufacturing cost and also int c transportation of theanchors to thepoint where they are used.

The invention has for further objects to provide a simple and economicalY rail anchor consisting of a flexible steel. yoke and a malleable ironjaw member.

The invention has for further objects such other new and improvedconstructions, arrangements and devices relating to rail anchors as willbe hereinafter described and.

rail, the letter be- 8 are views corresponding to Figs. 1 and 2,respectively, illustrating a modification; and

Fig. 9 is a sectional view on line 9-4) of parts in the several figuresof the drawings. Referring first to Figs. 1 to 6 inclusive, A

represents a railroad rail, the base flange of which 1S designated B,and G one of the cross ties on whichthe rail is laid. The rail anchorconsists'ot two members D (Fig. 5) and E (F 1g. 6). The member D ably amalleable casting and consists of r jaw 10, a tie abutting flange11,31ltl3. wedge 1:2, which latter preferablyincreases both in width andin thickness in the direction toward the tie abutting flange. The memberE consists preferably of a stripof steel (like characters of referencedesignate like is preferbent at one end so asto form a book 13 extendingaround'one edge of the rail base and at the other with a hook is. Thehook-14 is preferably formed by giving an oblique bend to the metal sothat the interior of the hook has generally the contour of wedge 12. Theyoke E is preferably bent transversely at 15 so tbatwith the hook13-01:. the rail, the inclined portion 16 of the yoke has a slant withrespect to the plane of the base flange of the rail greater than thatwhich it has to assume when the hook it is in operative engagement withthe jaw member D. The device is applied to the rail by placing themember D a 'ainst tie-C, slipping the yoke ineinber under the rail untilthe hook 13 is brought into engagement with one edge of the base flange,their driving the yoke toward the tie with hook 14 extending around thewedge 120i the jaw member.

The normal set of the inclined portion 16 v of the yoke with respect tothe hook 13 is indicated by the dotted lines in Fig. 1. When the hook 14is engaged with the wedge 12 and the. yoke driven yoke is flexed. It,therefore, exerts a constant stress upon thejaw niemberwhich opcrates toabsorb vibration and any slight looseness that might otherwise resultfrom di tl'erences in expansion and contraction as between the rail andthe parts of the anchor, or from a slight retrograde movement of theyoke, or from other causes, thereby making the hold oi the device on therail much more permanent and reliable than it would othervise be. Thejaw formed with a leg 17 which is bent down toward the tie, the

member is preferably after the yoke has been driven upon wedge 12 so asto provide a positive sto to prevent the yoke from backing down t ewedge. However, this tendency to back down the wedge is checked and ina, ;large measure eliminated by making the yoke flexible and giving it abending strain when. applied to the rail. The full lines; Fig. 1', showthe normal position of the lug 1:? and the dotted lines the position"which "the-lug assumes when bent down behind the yoke.v The wedge 12' ispreferably made hollow. For

example, the under side is formed with a cavity 18*{Fig 4). The metalforming the wdge is, therefore, relatively "thin so that The slightcrushing in of wedge 12 does no harm; in fact, when occurring itprovides a seat for the yoke which tends to prevent the yoke frombacking down the wedge The modification shown in Figs. 7 to 9 infelusive, relates only to the means for providmg a positive stop for theyoke onthe jaw member. The latter, designated 1), is formed with aperforation 19 preferably extending through. the wedge portion 12 ofconstruction and arrangement of said member into which a key 20 isdriven after the yoke member E has been forced toward the tie as far aspossible. The parts of the device are preferably designed so that whenthe yoke member has been. driven toward the tie as far as can beconveniently done with a hammer, or the like, the edge will stillproject slightly over the opening 19. By driving the key 20 into placethe yoke is forced farther up the wedge. The lower end of the key 20 ispreferably slotted, shown at 21. or otherwise weakened so that it may bebent over into a locked posi-' tion as indicated by the dotted lines inFig. 9.

While I have described my invention in certain preferred embodiments, itwill be understood that minor changes in the form,

parts might be made without departure from the invention. Therefore, Ido not wish to be understood as limiting the invention to the exactconstructions described and shown except so far as so limited by theexpress language of the claims.
